x86/apic: Remove the duplicated tracing version of local_timer_interrupt()
The two NOP5s are noise in the rest of the work which is done by the timer
interrupt and modern CPUs are pretty good in optimizing NOPs anyway.
Get rid of the interrupt handler duplication and move the tracepoints into
the regular handler.
